After the glue is applied, this Rabobank mechanic spreads it out on the tire bed with an old toothbrush that's soaked in solvent. The solvent keeps the brush was getting gummy and also makes the glue easier to spread in a thin layer.

Rabobank riders' preferred air pressures were noted on this piece of paper tacked over the workbench.

(Jonny Irick)

32 / 84

Rabobank's air compressor was connected to this handy inflator for accurate pressure readings. It doesn't shut off automatically like the handheld Craftsman compressors often used in 'cross circles but the digital readout provides finer resolution than typical analog dials.

Rabobank's team mechanics glue a lot of tubulars. Keeping it in bulk inside this handy bottle is a lot easier than using individual tubes or even the large cans that many companies offer.

(Jonny Irick)

40 / 84

The spout of the Rabobank team mechanics' tubular glue bottle is actually a presta valve with the guts removed. If it gets clogs, it's easy to just replace the stem and carry on. Otherwise, a standard valve cap keeps the glue from curing prematurely.

This is how Rabobank team mechanics apply glue to a rim.

Team trucks have lots of room for storage. Tucked away down in this Astana vehicle is a compressor, various hoses, and lots of cleaning supplies.

(Jonny Irick)

54 / 84

The Astana team bus is equipped with a double shower stall so riders can get cleaned up even before they arrive back at the hotel after a race. Two riders are meant to be in there at once so teammates must clearly be comfortable with each other.

Wheels are set in the respective trays on Katusha's measuring jig. There's another little bit at top right that plugs into the bearing preload cap on the team's Shimano cranksets to provide a reference point.

Katusha mechanics don't use a truck. Instead, they use a converted touring bus as there are fewer restrictions on European roads.

(Jonny Irick)

72 / 84

The inside of the Katusha team mechanics' bus is a little more cramped than the usual box truck but there's still plenty of room for bikes, wheels, and other gear. Two custom painted frames are ready to be built.
